' 12 Claims. (or; 1'29'- 7-)' This invention relates to loose leaf binders having means to shift one or more sheets within a binder relatively to the rest of the sheets, without disturbing the relationship between the sheets being: shifted. Although the invention is applicable to loose leaf binders of any kind, itis of particular advantage in connection with so-called visible index binders in which a plurality atively short sheets are arranged in vertically overlapping relationship so that a predetermined area on each sheet is exposed whenever the is opened.

binder In order toobtain the full benefits of loose leaf visible index' binders it is essential that the sheets be maintained in some definite arrangement. When it is necessary to insert a new sheet between any two sheets in the binder, it is saryto shift all the sheets on one side necesof the proposed insertion space up or down one space to maintain the visibility feature of the binder.

Although shifting of this type, that is from one position to another within the same binder, is generally confined .to visible index binders, itis quite often desirable to provide other types of the sheets from one binder to a different I binders with means to shift all or a portion of binder.

It is an object of this invention to provide means'for facilitating the insertion, removal." and rearrangement of 'one or more sheets in a binder without disturbing the relative arrangement of the remainder of the sheets.

1 It isa further object of this invention to pro vide means for shifting one or more-of rality of sheets. impaled on post's'or prongs in a binder either upv or down. with respect other shee'ts'in the binder without removi of the sheets from the, posts.

to the ng any It is a-further object of this invention to; 51 vide a removable post supportingbar forming a part of the binder adapted to carry all or a portion of the sheets of the binderand to fit universally into any similar binder of the same size so that anydesired number. of .sheets.,may be shifted from onebin'd er to a different binder. of

the same kind without disturbing .the relative arrangement. of the sheets or removing" the sheets from the posts or prongs upon which they areimpaled in. the binder.

It is a further object of this invention to ro vide means for shifting a portion ofthe contents of a loose leaf binder with respect to the rest of the contents so f'that the binder may be closed before the shifting operation is completed withoutany possibility of damaging" eith shift mechanism or the sheets.

Wil

*lt is a further objectof this invention toprovide a loose leaf binder embodying a removable shift bar that is inexpensive 'to manufacture,

simple and efficient in operation, and is capable Figure 4 is a cross section taken on' the line IV -IV of Figure 2, with parts broken away to facilitate the illustration;'

Figure 5 is a perspective post carrying bar V Figure 6 is a rose section taken on the line VI- -VI of FigureB'; and

F'igure'Tis a cross sectiontaken on the line VIIVII' of Figure 2.

i In the drawings the reference numeral 1 desig ates the back member of the binderwhichcomprises'two sections 2 and} hinged togetherat 4. Cover members Bend 6 are hinged-to the back sections 2' and 3 at "7 and 8, respectively. The back section 21 is provided with'end members9 and 10, and the back section 3 isprovided'with endmembers 11 and 12. n Anfarcu a'te plate 13 shaped notches 14 isriveted or welded tothe inner face of each of the end membersaand l0. 7 A rod 15 is: rotatably mounted on pins; or trunnions' 16 extending through the. end members l1 and 12 A pawl l'l isfixed to the rod 15 adjacent'each end-thereon. One .end of the pawl ,l'l is provided with a ltooth 18 adapted to engagev with the notches 14' in the plate13jto hold the back sections 2 and 3 in any of several'predete'rmined positions. The other end of. the pawl; 1.7. is provided with .a .finger piece 19 so thatfth eitooth 18 may be readily disengaged from the notches 14. A coiled spring20 encircles eachend of the rqd 'laand has one end secured to'a-pin 2l projecting from -the innersurfaceof thepawll'l'. The other-endof the spring ZO butts against the wall of the {back section 3. The spring-exerts constant pressure urging the'tooth 18 into en-j-. gagement :with the notches 14 so that the back sections may be closed without manipulation of thei'pawl-fl'li The shape"ofothe' itoothi 18 and 'iew of the removable back sections 2 and 3 until the finger piece 19 is depressed to move the tooth 18 out of engagement with the notch 14. Since both pawls 17 are fixed to the rod 15, manipulation of either finger piece 19 is sufficient to move both pawls 17 to disengage the tooth 18 of each from its respective notch 14.

The plate 22 is of inverted U-shape and carries a series of arcuate shaped sheet retaining posts or prongs 23. The base portions of the posts 23 are flattened, as indicated at 24, and are welded to the plate 22. The free ends of the posts .23 are pointed, as indicated at 25, to facilitate positioning a plurality of sheets 26 thereon. As shown in Figure l, the sheets 26 are considerably shorter than the binder and are arranged on the posts in overlapping relationship so that a definite predetermined area at the lower edge of each sheet is exposed, and the major portion of each sheet is coveredxby. the preceding sheet. Any "desiredindicia maybe typed on the exposed surface of the sheets andconstitute a visible index for the contents of the binder. Equalizer sheets of any desired kind may be inserted between each bank of sheets to maintain a uniform level for the'sheets. I

Sheet retaining posts 27, similar to the posts 23 have their flattened base portions 28 welded to a removable ,bar 29. The bar 29 is substantially of inverted U-shape, but has one edge bent back on itself, asindicated at 3Q,-to form an abutment for a purpose hereinafter described. The longer .wall of the bar 29 hasportions cutaway to form two groups of recesses 31 which are adapted to cooperate witha pair-of projections 32 secured to the inner face of-the back section 2 to position the bar 29. The bar 29 is shown as having three recesses 31 in each group,.although the number might be varied at will. Y

Theplate 223nd the bar29 are each provided with a series of recesses 32't0 receive the pointed ends of theposts carried by .the' other. The number of recesses 32' between adjacent prongs is the same as the number of recesses 31in each group, and the spacing is the same. Since the spacing of the recesses 31 determines the units of distance the -bar 29 may be moved, the pointed ends of each post will always be received in a recess in theplate 22 or the bar 29 regardless of the particular position .of the bar 29 when the back sections 2 and 3 are closed.

The .bar.29 is maintained in place by a lock bar.33 which includes an angular member 34 perma'nently secured to a fiat member 35. .The

angular member. 34 is provided with a flange 36 adapted to interlock with the bent over member 30 to'prevent any possibility of accidental displacement of the'bar 29. The lock bar 33 is pivoted at eachend to a toggle link 37 as indicated at 38. 'The opposite end of the toggle link 37 is pivoted'at39 to a bracket 40 rigidly secured to the back section 2. v p

' One end' of the flat portion 35 of the lock bar 33 extends "through a slot 41 cut out of the end member 9. A 'fingerpiece 42'issecured to the end of the lock bar 33. The lock bar'33 is provided with a shallow recess 33' (Figure 2) to allow it to have sufficient transverse movement to releasethefiange 36 from its interlocking engagement withathe abutment '30' without binding on the pivot pin 39. 'As shown in Figure 2', the toggle link-37 is positioned slightlyoff center when the bar'z33 'is' in looking position. Although theitoggle connection is preferred, it will-be obvious that the movement of the lock bar 33 might readily be guided by a suitable cam slot cooperating with pins projecting from the brackets 40. In either case the frictional contact between the lock bar 33 and the removable bar 29 is generally sufiicient to maintain the removable bar in position.

The plate 13 adjacent the spring member 43 is :cut away, asindicated at 44, Figure 4, to permit the flat portion of the spring to lie adjacent the inner surface of the-end member 9. As shown in Figure 7. thespring member 43 is provided with a projection 45. The flat portion 35 of the lock bar 33 is provided with two recesses 46 and 47. The projection 45 springs into the recess 46 to maintain the lock bar 33 in locked position and into therecejss 47 .to maintain it-in unlocked'position'. .1

The operation of the binder maybe summarized as follows,assuming that it is desired .to insert asheet 26 between the two sheets designated in Figural as .48 and 49: I

The sheet 48 and all preceding sheets aremoved to the. left side of the binder while the "sheet 49 and all therebelowremain on the right side of the binder as shown in Figurel. Eitherfinger piece 119 is then depressed to release the pawl teeth 18 from engagement with the notches. l4 and the-backsectionsZarfd v3ia1'e-;separated to the limit of, theirrmotion. Thesheet .tobe added'may then be positioned on .thesheetretaining posts 23 in .the same position-previously Lo'ccupied by .the sheet 48. The 1ocking'b1ar33 .isrthen moved to unlocking position, andthe :removable bar .29, with the sheet 48 and those preceding it, isgremoved from the ibacklsection .2 and reinserted in positionwithrthe projection 32- engaging the recess 31 just below-the recess in which items originally engaged. cfIhelock bar is then.moved tolocked positionand theiback sections 2 and 3 .are:closed.

Although'the above .anoted :steps are suificient to arrange all ,of the sheets in :the .desired.rela-. tionship,'the.removable bar 29 should be brought backto its :normalposition. .Ihismay be done by transferringallthe sheets to theright'handportionzof :the .bindeniseparatingithe back sections 2 and 3, unlocking thejlock bar 33,rem'oving the bar. 2 9.andrepositioningr'itl inits original position, lockingitherlock bar 33,and then closing'the back sections ;2 and 3. Because of the fact that the number-:of recesses .32 correspond withthe num ber' of recesses .31 :inone group, the'binder. may be closed regardless of the' position'ofthe removable bar-29 without'a nypossibility of da'mage tothe binder orposts'. -In view of the fact thatthe post carrying bar 29 is entirely separate from the-rest of the binder; it will be obviousthat said bar'may be "shifted from "onejbinderto another binder of the same are without the necessity of moving the sheets off the posts 27.
